Integration and formal representation in civil engineering supervision based on data-driven

In the civil engineering supervision, the management processes about personnel, materials, quality, safety, schedule and etc. are complex, which include large amount of data, involve more participants, and timely coordination and feedback is difficult. In this paper, we propose the data integration idea based on data-driven, which could guide the whole life cycle of civil engineering supervision from the top-level data organization, supervision of business processes, the interactive units and the users, the four-elements method TDTM and so on. Then, the data integration algorithms of civil engineering supervision are put forward to integrate the civil engineering supervision data from outside to inside and from coarse-grained to fine-grained, eliminate contradictions and redundancy and ensure data consistency. Finally, the civil engineering supervision data entities are determined, and we further analyze and discuss its query and report, data maintenance and conversion, and compare the functions in the different supervision platform. The civil engineering supervision unified data platform proposed could maintain the independence of the data, have the good scalability and support the more functions.
